I caught a single scene of this movie, flipping channels through [Korean] TV over the summer.
In it, two men are having a fight in some (grey-ish) mud, in the daytime, in front of a quarry/cliff/dried riverbed or something. One of the men is armed with a knife, I think there’s a revolver on the ground or something. The only other person present (seems to be the female lead?) a brunette who seems heavily invested in what’s going on. The fight ends with (I think) one of the men dead and the woman shot. The last part of the scene I saw was the victor of the fight standing alone, with the woman’s body limp in his arms, as a few men on horseback arrive.
This channel shows a lot of 60s-era Westerns, but by the time I went back to check their broadcast history, it wasn’t available any more. Also, I’m unsure of the language spoken (definitely European), but it wasn’t English. (Not to say it didn’t have a dub, just that this broadcast wasn’t the English dub).
Sounds like Bury Them Deep (1968) with Craig Hill.
The knife fight in the mud between Hill and Giovanni Cianfraglia is the best scene in the movie and one of the few action scenes which isn’t borrowed footage.
Yep! I had just come across the same poster highlighting that fight scene too. Scrubbing through it, it looks like if I’d caught any other scene, I wouldn’t have taken notice; but I’m gonna give it a fair shake and full watch anyway.
